HIGH REFRACTIVE INDEX SILICONE COMPOSITIONS |
摘要 |
Organosiloxane compositions curable to optically clear, high refractive index elastomers are disclosed. The cured compositions have superior post-folding high resolution recovery making them suitable for fabricating foldable intraocular lenses used in small-incision ophthalmic surgeries. The organosiloxane compositions include first and second vinyl terminated organosiloxanes differing in molecular weights, each containing diphenylsiloxane and dimethylsiloxane, and, in addition, fumed silica, a crosslinking reagent, a platinum containing catalyst, and optionally an ultraviolet absorbing compound. |
